Key Features
Energy Recycling
The system features regenerative technology that recovers the large amount of power normally dissipated as heat during battery cycling. This not only reduces energy consumption but also ensures stable test performance without introducing harmonic interference to other equipment. The recovered energy can be fed back to the grid for reuse, easing the load on power infrastructure, reducing thermal management challenges, and aligning with green energy policies.
Discharge Energy Recovery
– Energy can be recycled back to the grid or internal loads, with recovery efficiency >90%.
– Low heat output reduces air-conditioning demand and lowers operating costs.
– At rated power, the power factor (PF) exceeds 0.95.
The system delivers high power testing capability even in space- limited environments. A single cabinet achieves a maximum power density of 106kW/m³ while weighing only 740kg, minimizing footprint and saving valuable floor space.
Suitable for Space-Constrained Applications
The 17050 model can be configured to communicate with stand- alone units and DC sources designated by Chroma. With Chroma’s Battery Pro X software, each channel can perform independent testing to meet a wide range of battery pack requirements. The system also supports integration with chambers and chillers, and unlike fixed rack-based setups, offers greater flexibility for use in space-limited test environments.
BMS Communication Functions
– Uses the Chroma 80700-5 standard chassis integrated with the A692017/4CH CAN (FD) bus communication card module to perform BMS communication.
– Channels can be bound to the BMS to capture and record DUT data, with cutoff and protection logic executed in synchronization with the acquired data.
Versatile Programming
The Chroma 17050 system, together with Chroma’s Battery Pro X software, offers flexible programming with an intuitive interface for editing and executing test steps. The software supports graphical creation of test programs, predefined test modules, real-time data monitoring, and seamless integration with external equipment. These features make test configuration more accurate and more efficient, meeting the needs of demanding applications.
With Chroma’s Battery Pro X software integrated with third-party hardware, abnormal conditions can be detected in real time, triggering charge/discharge protection to stop the test. Combined with a BMS designated by Chroma and a data logger, the system achieves sampling latency of less than 10ms. This capability supports battery performance prediction, degradation analysis, and protection parameter verification, while ensuring accurate test status monitoring, data recording, fault diagnosis, and safety protection.
